Are you considering using a wood chipper to process rubber materials, like tires or conveyor belts? This question often arises, but the answer may surprise you.
No, wood chippers are not designed to handle rubber. Rubber’s unique properties, such as elasticity and density, can severely damage the machine and create safety hazards.
Understanding why rubber is unsuitable for wood chippers is crucial. Let’s explore the consequences of misfeeding rubber into these machines and discuss safer alternatives.

Why Is Rubber Incompatible with Wood Chippers?
Rubber and wood differ significantly in their physical properties. While wood is brittle and cellular, rubber is elastic, dense, and fibrous, creating challenges for wood chippers.
Rubber’s elasticity resists the cutting action of wood chipper blades, leading to increased heat, friction, and potential damage to the equipment.
Rubber’s composition can cause blades to dull rapidly, screens and anvils to clog, and rotors to lose balance. This results in costly repairs and operational downtime. The machine’s motor may also overheat, reducing its efficiency and lifespan. For more on the risks of misfeeding, visit our blog.

What Are the Risks of Chipping Rubber?
Using a wood chipper for rubber introduces numerous risks, from equipment damage to safety concerns for operators.
Rubber can cause kickback, projectile risks, and overheating, making it a hazardous material to process in a wood chipper.
Equipment Damage
- Blade Damage: Rubber dulls or chips blades, which are engineered for wood.
- Clogged Screens: Rubber stretches and wraps around components, leading to blockages.
- Overloaded Motors: Rubber’s resistance puts excessive strain on the engine, risking breakdown.
Safety Hazards
- Kickback: The elasticity of rubber can cause dangerous material recoil.
- Projectile Risks: Damaged components can eject material, posing threats to nearby workers.
- Fire Hazard: Friction-induced heat can ignite rubber, creating a fire risk.

What Are Better Alternatives for Processing Rubber?
If you’re looking to process rubber, wood chippers are not the right tool. Instead, consider specialized equipment designed for non-wood materials.
Industrial shredders are the best alternative for processing rubber like tires or conveyor belts. They are engineered to handle dense, elastic materials safely and efficiently.
Industrial shredders have reinforced blades and components designed to manage the unique challenges of rubber. They minimize wear and tear, ensuring both safety and cost-effectiveness. For a deeper dive into this topic, explore Wikipedia’s guide on industrial shredders.
What Materials Should Never Go into a Wood Chipper?
Rubber isn’t the only material you should avoid chipping. Other unsuitable materials can also damage your equipment and jeopardize safety.
Inorganic materials like rocks, metals, and plastics should never be fed into a wood chipper. These materials can cause severe damage and contamination.
Examples of Materials to Avoid
Material | Why It’s Unsuitable |
---|---|
Rocks | They dull blades and damage screens. |
Metals | Can chip blades and create fire hazards. |
Plastics | Melt and clog screens, contaminating output. |
